[solved] what debug flags are useful for most packages besides -g ?

I've been doing debug builds packages for many of my installed aur packages for a while using options=(debug strip) .

My /etc/makepkg.conf had "-g -fvar-tracking-assignments" which was default for pacman 6.0.1-3 .
The symbols that added helped a lot with solving bug reports for trunk versions of software I use (only complaint I sometimes got was having too much debug syymbols in crash logs ).

I don't compile anything with clang, so the fact that clang doesn't support "-fvar-tracking-assignments" doesn't bother me for my personal usecase ..

In pacman 6.0.1-4 "-fvar-tracking-assignments" was removed from /etc/makepkg-conf .

I looked at man gcc and found there are lots of debugging options.


My software troubleshooting capabilities are mostly limited to describing, bisecting , testing and such but understanding crash logs or core dumps is not my forte.

For now I'm sticking to "-fvar-tracking-assignments" , but I'd like opinions from other forum users what debug flags they think are useful.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.
Did you use the guided installer ? If yes, I can't help you.

(A works at time B)  && (time C > time B ) ≠  (A works at time C)

Have you read https://gitlab.archlinux.org/archlinux/ … equests/87 are you not building with any optimization?  In which case you could use -Og.

Nope, hadn't seen that.

I did look at gcc man page again and now understand a bit better.

I bulid with -O2 so -g should be enough to get useful symbols in the logfiles.
